Abstract

A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

First claim

What is claimed is:

1. A system comprising:
a detector configured to detect activity data indicative of activity of a user during an activity period; and
a processor configured to:
determine a number representative of the detected activity data during the activity period;
determine a ratio based on a comparison of the determined number and a maximum number for the activity period; and
generate a unitless activity value based on the determined ratio.

2. The system of claim 1 , further comprising an enclosure that at least partially houses each one of the detector and the processor.

3. The system of claim 2 , wherein the enclosure is configured to be worn on a wrist of the user during the activity period.

4. The system of claim 1 , wherein the processor is configured to generate the unitless activity value by multiplying the determined ratio by a range number.

5. The system of claim 1 , wherein the processor is further configured to:
determine a type of activity of the user performed during the activity period; and
determine the maximum number for the activity period based on the determined type of activity.

6. The system of claim 5 , wherein the processor is configured to determine the type of activity by detecting at least one press of a button.

7. The system of claim 6 , further comprising an enclosure that at least partially houses each one of the detector and the processor and the button.

8. The system of claim 7 , wherein the enclosure is configured to be worn on a wrist of the user during the activity period.

9. The system of claim 5 , wherein the processor is configured to determine the type of activity by processing at least a portion of the detected activity data.

10. The system of claim 1 , further comprising an output component configured to present the generated unitless activity value to the user.

11. The system of claim 10 , wherein the output component comprises at least one light configured to present the generated unitless activity value to the user.

12. The system of claim 10 , wherein the output component comprises at least one speaker configured to present the generated unitless activity value to the user.

13. The system of claim 10 , further comprising an enclosure that at least partially houses each one of the detector and the processor and the output component.

14. The system of claim 13 , wherein the enclosure is configured to be worn on a wrist of the user during the activity period.

15. The system of claim 1 , further comprising:
a wireless transmitter configured to wirelessly transmit the generated unitless activity value;
an enclosure that at least partially houses each one of the detector and the processor and the wireless transmitter; and
an output component, external to the enclosure, configured to:
wirelessly receive the transmitted unitless activity value; and
present the received unitless activity value to the user.

16. The system of claim 15 , wherein the output component comprises at least one light configured to present the generated unitless activity value to the user.

17. The system of claim 15 , wherein the output component comprises at least one speaker configured to present the generated unitless activity value to the user.

18. The system of claim 15 , wherein the output component is configured to be worn on a wrist of the user during the activity period.

19. The system of claim 1 , wherein the processor is configured to determine the number representative of the detected activity data during the activity period by intergrating power spectral density of acceleration data of the detected activity data over the period of time of the activity period.

20. The system of claim 1 , wherein the determined number is a function of gravitational force.

21. The system of claim 1 , wherein the detector comprises at least one accelerometer.

22. The system of claim 1 , wherein the unitless activity value is based on an intensity of the activity of the user during the activity period.

23. The system of claim 1 , wherein the processor is configured to generate the unitless activity value by multiplying the determined ratio by a range number.

24. A system comprising:
a detector; and
a processor configured to:
sample the detector to obtain data during a time period;
determine a number representative of the obtained data for the time period;
increase an accumulator number by the determined number;
determine a ratio based on a comparison of the increased accumulator number and a maximum number for the time period; and
generate a unitless activity value based on the determined ratio.

25. The system of claim 24 , further comprising:
an output component configured to present the generated unitless activity value to a user; and
an enclosure that at least partially houses each one of the detector and the processor and the output component.

26. The system of claim 25 , wherein the enclosure is configured to be worn on a wrist of the user during the activity period.

27. A system comprising:
a detector configured to detect activity data indicative of activity during an activity period;
a processor configured to:
determine a number representative of the detected activity data during the activity period; and
generate a unitless activity value based on the determined number and a maximum number for the activity period; and

an enclosure that at least partially houses the detector and that at least partially houses the processor.

28. The system of claim 27 , further comprising an output component configured to present the generated unitless activity value, wherein the enclosure at least partially houses each one of the detector and the processor and the output component.
